"Zangnan is China's territory," spokesperson Wang Wenbin said in response to a question on the visit by Indian Home Minister Amit Shah.
"The Indian official's visit to Zangnan violates China's territorial sovereignty, and is not conducive to the peace and tranquillity of the border situation."
China and India have had several skirmishes over the disputed border and clashes in mountainous regions in recent years have seriously strained ties.
